The management of sternal wound complications after median sternotomy has been revolutionized by aggressive debridement protocols and muscle flap transposition (1). The potentially lethal sequela of cardiac surgery has focused the attention of plastic surgeons almost exclusively on refinements in treating such chest wounds (1,2). According to the National Cardiac Surgery Database (1994), deep s...

We report the case of a patient who noticed muscle weakness in his left arm 5 years earlier. On examination, a biloculate mass was observed in the left supraclavicular area, and Tinel's sign caused paresthesia in his left arm. Magnetic resonance imaging showed a continuous, multinodular, plexiform tumor from the left C5 to C7 nerve root along the course of the brachial plexus to the left brachi...

In Escherichia coli, the frequencies of IS50 and Tn5 transposition are greater in Dam- cells than in isogenic Dam+ cells. IS50 transposition is increased approximately 1,000-fold and Tn5 transposition frequencies are increased about 5- to 10-fold in the absence of Dam methylation. However, in cells that are deficient for both integration host factor (IHF) and Dam methylase, the transposition fr...

: Second surgery for postoperative complications after lung resection is one of the important issues that thoracic surgeons must overcome. Chronic empyema resection, which caused by bronchopleural or pleural fistula remains a challenge in modern medicine. Especially cases decortication not indicated, treatment difficult, hospitalization prolonged, and condition sometimes life-threatening. Surgi...

To evaluate the long-term surgical outcomes of anterior transposition of the inferior oblique muscle (ATIO) in the treatment of vertical deviations resulting from superior oblique palsy (SOP). We retrospectively studied seven consecutive patients who had undergone ATIO for the treatment of SOP. A follow-up of at least five years after the operation was required to be included in the study. In r...

One possible model to study genome evolution is to represent genomes as permutations of genes and compute distances based on the minimum number of certain operations (rearrangements) needed to transform one permutation into another. Under this model, the shorter the distance, the closer the genomes are. Two operations that have been extensively studied are the reversal and the transposition. A ...

OBJECTIVE Lung resection for complex aspergilloma (CA) carries high morbidity and mortality and remains controversial in high-risk patients. Cavernostomy followed by muscle-flap plombage has been recommended for patients considered unfit for resection, but subsequent muscle-flap atrophy may be a main cause of failure. We reviewed the place of a limited thoracoplasty in association with that pro...

A genetic complementation system is described in which the complementing components are close together in a single linear DNA fragment; the complementation situation is temporary. This system is useful for providing transposition functions to transposition-defective transposons, since transposition functions act preferentially in cis. The basic procedure involves placing a transposition-defecti...
